I picked this up at the flea market today for 2$
It was pretty ruff shape so I lapped it on a disc sander, I will say one thing it "smoked" up my entire garage with dust. Which is not usual all my other Fleamarket hones have i lapped the same way and the others never produced ANY dust. It is Very very smooth and laps very easy, a diamond lapping stone cuts through it like butter.
Size = 1 1/8 wide X 5.5 long and it was about 3/4 inch thick.
Any help with an ID would be helpfully.
